How many lumens do I need for a bright room ?

The brightness you need really depends on your environment. If you’re watching movies in a completely dark room, you don’t need an extremely bright projector—something in the range of 1,500 to 2,500 lumens will usually do the job just fine. But things change when you introduce light. If your room has windows, lamps, or overhead lighting that you can’t fully control, you’ll want to go for 3,000 lumens or higher. This extra brightness helps the projector’s image cut through the ambient light so colors don’t look faded or washed out. In simple terms: the brighter your room, the more lumens you’ll need. That’s why projectors designed for classrooms, offices, and outdoor use often advertise very high brightness levels—they’re built to deliver a clear, vibrant picture even when total darkness isn’t an option.
